Have you tried https://codecombat.com? I think it's a YC startup. I think that's the closest to what you're looking for. I tried it back in the day, and it was OK.

It's not exactly programming, but I think https://vim-adventures.com/ is the best example of a game that teaches a skill.

Just making a good game is difficult. Just making good teaching content is difficult. So trying to both simultaneously will be at least doubly as difficult.

As for my VR scripting idea, teaching programming isn't the main goal. When VR becomes the next social media, the content creators will either need to do a lot of manual work constructing experiences or learn how to program. It's really hard and messy to create an interactive VR experience without knowing how to program.

So my VR scripting tool/platform will solve a painful problem. A lot of creators won't be programmers, so I think teaching them how to program/use the tool via a game would be helpful.
